[s-cars] How much are the RS2 manifolds going for now?

[chad clark]

That is the correct story Dave. After 2.5 years the manifold decided it no
longer liked the cylinder head and began pulling away near exhaust port #1
and #5. Heard the dreaded tick tick tick until the manifold warmed up and
sealed the small gap. This is with proper turbo warm up and cool down. It
didn't look like a warped 2x4 but I think the machine shop took off a few
thousandths. And as you stated, I have always been told that once planed
flat, it shouldn't warp again as it is now no longer "green". Hell, even the
stock manifold lasted some 70k mi with no cracking or warping problems and
looks perfect today sitting on my shelf.  HTH,
